TangentLine(l, point(A, 0, 1), circle(c, [point(C, 0, 1), 1]))

Under geometry package if I use the command Tangentline, and if I want to change either the point of the circle, then 

Error, (in geometry:-line) the first argument is expected of type name

How I make it overwrite l each time? So I don't have to rename the tangents each time?
